(3) Operation of Variable Display Device The operation of the variable display device 60 having the above configuration will be described with reference to FIGS. 10 to 14. The stepping motor (SP motor) provided in the variable display device 60
77a-77c and phototransistor (sensor) 98a
To 98c are input / output circuits (I / O) as shown in FIG.
It is connected to the microcomputer 130 via 134. The microcomputer 130 includes an MPU 131 capable of executing a control operation in a predetermined procedure,
ROM 13 for storing operation program data of U131
2 and RA that can write and read necessary data
M133. The microcomputer 130 has a start switch 1 via an input / output circuit 134.
6a to 16c, stop switch 9, variable winning prize ball device 110
Solenoid 114 and a specific winning area 120 described later
Is connected to a V winning ball detector (V sensor) 122 provided in each of the. Instead of the stop switch 9, a stop signal may be generated by a timer that measures a certain time.

When the power is turned on, the variable display device 60 performs the operation shown in FIG. That is, it is determined whether or not the power is turned on (step S).
1) When it is turned on, the driving of all the stepping motors 77a to 77c (hereinafter, referred to as SP1 to 3motors) is started (steps S2, S2 ', S2 "). So
The processing for the SP1 motor will be described.

When the SP1 motor is driven in step S2, it is determined whether the value of a step counter SC1 provided in the microcomputer 130 is a reset value (step S3). Incidentally, the stepping motor is rotated by repeatedly sending four step signals as shown in FIG. That is, in step 1, the signal of (1100) is used, and in step 2, (011)
0), a signal of (0011) in step 3 and a signal of (1001) in step 4 are transmitted.
Because it rotates 3.75 degrees by the signal of the step,
The SP motors 1 to 3 make one rotation according to the signal of 96 steps. Therefore, if the number of pieces of identification information drawn on the rotating drums 76a to 76c is, for example, 12, then 1
An eight-step signal is sent to move one identification. Thus, the step counter SC1 detects the reset value of step 1 every time there are four step signals. Therefore, the reset value in step S3 is determined by the step of the stepping motor in step 1 (11).
00)).

When the step counter SC1 detects the reset value in step S3, it is determined whether or not the sensor 1 (phototransistor 98a) is ON (step S3).
4). This is determined to be ON when the sensor 1 detects the notch 89a. If the sensor 1 is not determined to be ON even after the predetermined time T has elapsed (step S6), an alarm process is performed (step S7) and an alarm is issued. This is because the SP1 motor may have failed or the sensor 1 may have failed.

On the other hand, when the sensor 1 is turned on, the number of steps n1 of the display data corresponding to the identification information to be displayed on the rotating drum 76a is called (step S5).
5) Thereafter, it is determined whether or not the value of the step counter SC1 is equal to the number of steps n1 of the display data (step S8). When the values are equal, the SP1 motor is stopped (step S9). The determined identification information is displayed.

Steps S3 to S of the SP1 motor described above
The processing of No. 9 is also applied to the processing of steps S3 'to S9' and steps S3 "to S9" of the SP2 motor and the SP3 motor, and predetermined identification information is displayed on the rotating drums 76b and 76c.

As described above, in this embodiment, when the power is turned on, the stepping motors 77a to 77c are unconditionally
Is rotated to display predetermined identification information and stop. Therefore, the defect of the variable display device 60 can be determined before the player starts the game.

Next, the operation of the variable display device 60 during a game will be described with reference to FIG. First, a hit ball wins the start winning prize openings 15a to 15c and the start switches 16a to 1c.
6c is turned on (step S1).
0), when turned ON, the data RD1 to RD3 taken out at random are determined (steps S11 and S1).
1 ′, S11 ″) The data RD1 to RD3 are SP
1 to SP3 motors. The data RD1 to RD3 are also data for specifying identification information displayed on the rotating drums 76a to 76c. For this reason, in this operation embodiment, the starting winning opening 15a ~
When the ball hits at 15c, the rotating drums 76a-7d
The combination of the identification information displayed in 6c is determined.

Since the following processing is the same for each SP motor, the processing procedure for the SP1 motor will be described. After the data RD1 is determined, the SP1 motor is driven (Step S12). In driving the SP1 motor, as shown in FIG. 14, a signal having a large pulse width is initially provided so as to gradually increase the rotation speed, and a signal having a small pulse width is gradually provided. this is,
This is performed because the starting torque of the SP1 motor is small. Also, when stopping the SP1 motor, it is preferable to stop the motor so as to gradually decrease the rotation speed. This is because if stopped suddenly, the inertia of the drum becomes larger than the magnetic attraction, and the drum may rotate extra.

After the driving of the SP1 motor is started, it is determined whether or not the sensor 1 has been turned on (step S13).
When turned on, the step counter SC1 is reset (step S14), and the step counter SC1 starts counting (step S15). Note that the reset of the step counter SC1 is performed when the reset value is step 1 (1100) and the sensor 1 is turned on as shown in FIG. The length of the cutout portion 89a is determined so that the sensor 1 can accurately detect ON at Step 1 (1100). To explain this, the stepping motor rotates while repeating start and stop every time there is a signal of one step, and thus always rotates while blurring. Therefore, the notch 8
If the length 9a is short, the sensor 1 detects a portion that has deviated from the notch 89a due to blurring.
Despite the case of (1100), no reset signal is issued, and accurate determination of identification information cannot be made. Therefore, the length of the cutout portion 89a is selected in consideration of the blur in the front-rear direction.

After the step counter SC1 starts counting,
It is determined whether or not there is a stop command signal by the stop switch 9 or the timer (step S16). When the stop command signal is present, it is determined whether or not the value of the step counter SC1 is equal to the value of the data RD1. It is determined (step S17). Then, when those values become the same, the SP1 motor is stopped (step S18). At this time, the identification information displayed on the rotating drum 76a is identification information determined according to the data RD1.

The processing in steps S13 to S18 is performed in steps S13 'to S13' in the SP2 and SP3 motors.
S18 'and steps S13 "to S18" are the same as those described above.
2 and RD3 are displayed.

In the above-described embodiment, the identification information to be displayed when the starting prize is won is determined.
After the stop command signal is received, the stop position may be detected to determine the combination of the identification information. This can be determined by counting the number of steps from when the sensor detects the notches 89a to 89c to when the SP1 to SP3 motor stops.
